My data sources were mostly government websites:
Federal Aviation Administration
Bureau of Transportation Statistics
U.S. Customs and Border Protection
Airports Council International – Aircraft Movements
Airports Council International – Passengers
Airports Council International – Cargo
I visualized the data using Microsoft Excel and added text and other numbers with Illustrator. You can read my full article with raw data and findings on my website here: www.asherfergusson.com/us-airports-most-likely-to-delay-your-flight/
